The invention discloses a flame spraying protection method for an aircraft slide rail part. A protecting clamp is used and comprises a clamp body and a slide rail protecting body. Before flame spraying, a connector of the slide rail part is fixed on positioning angle seats of a clamp base, the height of each connector protecting plate is adjusted to be appropriate, and accordingly, the part connector is prevented from being sprayed; curved-surface protecting plates are embedded in matched slide rail part cavities respectively and are fixed with a slide rail part body through positioning pins; the clamped slide rail part is subjected to flame spraying, and then the protecting clamp is dismounted.
Description
Technical field
The invention belongs to surface protection and surface peening field, it is related to a kind of flame-spraying protection of aircraft slide rail class part
Method and shield jig.
Background technology
Flame spray technique, as a kind of new surfacecti proteon and surface intensified technique, was sent out rapidly in nearly 20 years
Exhibition, it has also become a very active branch in the engineering field of metal surface.It is thermal source using flame, by metal and non-metallic material
Material is heated to molten condition, forms spray, be ejected on matrix under the promotion of high velocity air.The small molten granule of injection hits
Hit on matrix, produce plastic deformation, become the depositing coating of superposition, this process is referred to as flame-spraying.These alterations of form
Granule superposition afterwards forms coating.Spraying possesses the prerequisite that coating stress state is converted to compressive stress from tensile stress.Spraying
The excellent combination property of part afterwards, antioxidation, hardness are high, wearability is strong, corrosion resistance is superior, coating is fine and close smooth.But
Aviation part required precision is high, in order to avoid spraying to non-spraying surface in spraying, causes the dimensional accuracy at non-spraying position
Change, impact assembling and other performances are it is necessary to being positioned, clamped and protected to part non-spraying position using special fixture
Shield.There is no special fixture, simply simple locating element, structure is simple and crude, and operation is random strong and makes when at present part being sprayed
With extremely inconvenience, non-spraying surface is protected to non-spraying region using heat reflective adhesive tape or other suitable materials, protection
Ability.
Part positioning is clamped in a kind of device, and is installed along with lathe, part being processed, this device
Referred to as jig.The fexible unit (as scroll chuck, index dial etc.) that some parts pass through on lathe just can meet processing will
Ask；For required precision is high, part that is being difficult directly to position on lathe clamping needs design specialized jig to meet plus
Work requires.
A lot of slide rail class parts are had on aircraft, such design of part is more complicated, in irregular shape, four surfaces of slide rail need
HVAF to be carried out, the joint of slide rail and slide rail vallecular cavity do not carry out HVAF.Four sprays of slide rail
Apply in surface, have three faces to have vallecular cavity, need during spraying to carry out mechanical protection to these three vallecular cavities；The same joint to slide rail
Protected or isolated.
HVAF technique can only spray a work surface every time, the present invention relates to the spraying of four work surfaces,
Require this four faces to be placed in the optimum position of convenient spraying as far as possible, and in four work surfaces, have three faces to have vallecular cavity, need
Carry out mechanical protection, these are required for being realized on a sleeve clamp.Slide rail joint does not spray it is also desirable to mechanical protection,
And will be in slide rail joint positioning and clamping, these all realize really being difficult on a sleeve clamp, and this is accomplished by new structure
To complete.
Content of the invention
The purpose of the application is to provide a kind of flame-spraying guard method of aircraft slide rail class part and shield jig, main
It is used for the HVAF of the multiple work surface of aircraft slide rail class part, and realize the protection to non-working surface.
For reaching object above, the present invention is to adopt the following technical scheme that.
A kind of flame-spraying guard method of aircraft slide rail class part it is known that this part theoretical profile it is characterised in that：
1) there is a shield jig, this shield jig is made up of clip base and slide rail protective, and described clip base contains fixture bottom
Seat, is fixed with the positioning angled seat of joint element in clamp base, is additionally provided with joint on the peripheral clamp base of positioning angled seat
Protective plate；Described slide rail protective, is made up of three curved surface backplates that the three face vallecular cavities that need to be protected with part slide rail are matched,
Each curved surface backplate is provided with location hole corresponding with part slide rail；2), before flame-spraying, the joint of slide rail part is fixed on
In the positioning angled seat of clamp base, adjustment protection of welded joints plate height to correct position, to prevent joint element to be sprayed-on；Again will
Curved surface protective plate is respectively embedded into the part sliding-rail groove intracavity of coupling, is fixed protective plate with part slide rail body with alignment pin；3) will
Step 2) the slide rail part after clamping removes shield jig after carrying out flame-spraying.
The beneficial effects of the present invention is：Clamp structure registration, clamping consolidate, and the non-spraying surface of part is carried out
Physical protection is it is ensured that part performance requirement；Structure is simple, easy to use, and is furnished with scalable catch, facilitates operator certainly
Row adjusts catch position, and preferably to spray to part, similar part can share a sleeve clamp, and versatility is good.
Accompanying drawing is described in further detail to the application with reference to embodiments.
